Abstract

PURPOSE:To reduce the volume of data and to preserve easily the data by installing newly a means which encodes the action of the subject of an animation and stores it. CONSTITUTION:With the use of an action stating language (ADL) 1 being a special compiler language for stating the action of a subject, a user produces an animation program. The produced program is translated into a sort of information available from epitomizing actions, which is called an intermediate code, by a stating language translating part 2. At this time, said part 2 not only stores the intermediate code in an intermediate code memory 3 but also generates matrix data necessary for producing the action of subject and data on a shape at some point, and further stores them in a matrix data memory 4 and a subject/shape data memory 5. The intermediate code memory 3 stores information on actions, modifies and updates an address (pointer) in the memory in accordance with the contents and executes a control such as positioning the pointer at the top of a record to be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for creating a moving image, and more particularly to a method for storing video information expressed on each frame constituting a moving image.

[Prior art and its problems]

Creating a video involves sequentially creating still images of the object that appears in the video moving little by little, and continuously redisplaying these at a rate of several frames per second. This is achieved by

There are two ways to implement this method. One is a method in which a picture is prepared for each frame and drawn sequentially, and the other is a method in which a picture is prepared only for the key frames and interpolated between key frames using a function. In the former case, it is necessary to hold a huge amount of data, and in the latter case, there is a problem in that the function for realizing motion interpolation becomes large-scale.

[Purpose of the invention]

The purpose of the present invention is to eliminate the drawbacks of the prior art described above,
The object of the present invention is to provide a method for encoding and storing the movement of objects in a video, and to provide a video creation method that is effective in reducing the amount of data and storing data.

[Structure of the invention]

In a video creation method that creates a video by sequentially generating frame images, the present invention provides a translation unit that translates a program that describes the movement of an object using a unique description method into intermediate code that represents data of each frame, and an intermediate code memory section that stores intermediate codes; a shape data memory section that stores shape data of the object generated by the translation section at a certain point in time; and a shape data memory section that stores matrix data necessary for creating the motion generated by the translation section. and a matrix data memory section for calculating the data stored in the shape data memory and the matrix data stored in the matrix data memory based on instructions of the intermediate code read from the intermediate code memory section. It is characterized by comprising a calculation unit that creates shape data of the object at all points in time.

According to the present invention, motion is given to a two-dimensional or three-dimensional object by describing the motion of the object using a unique description method. At this time, information regarding the movement of objects in the video is held in the form of intermediate codes, and the video is created by converting this intermediate code. In other words, instead of storing video (data) for each frame,
It is stored in a code format that expresses the content of the video. Therefore, the part that creates the intermediate code and the part that converts the intermediate code can be separated, and once you create the intermediate code, you can create a video on any other system that has a part that converts the intermediate code. can be created, increasing the portability of video data.

[Detailed explanation of the configuration]

The principle of the moving image creation method according to the present invention will be explained using FIG.

FIG. 1 is a functional block diagram of the present invention. In the video creation method of the present invention, the user uses a motion description language 1 [^DL (^c
tion Definition Language)
) to create a video program. The created program is translated by the motion description language translation unit 2 into a form called an intermediate code that aggregates a type of object movement information. At this time, the translation unit 2 not only stores the intermediate code in the intermediate code memory 3, but also generates matrix data necessary for creating the movement of the object and shape data of the object at a certain point in time, and stores it in the matrix data memory 4 and the object/shape data. Each is stored in the data memory 5.

The intermediate code memory 3 is a part that stores movement information, and the intermediate code control unit 6 reads the data recorded here, and changes/updates the address (pointer) in the intermediate code memory according to the contents. Position the pointer at the beginning of the next record to be executed, activate the matrix calculation section 7, activate the display section 8,
The R-frame capturing section 9 is activated, or execution of the intermediate code is stopped or terminated.

The matrix calculation unit 7 accesses the matrix data memory 4 and the object/shape data memory 5 based on the matrix data address and the shape data address passed from the intermediate code control unit 6, and calculates the data between the shape data and the matrix data. A vector×matrix operation is performed to create new shape data and store it in the object/shape data memory 5 again. When this process is completed, execution returns to the intermediate code control unit 6.

The display unit 8 accesses the shape data memory 5 based on the shape address passed from the intermediate code control unit 6, and displays the RG
The B signal is output to the graph ink display 10. When this process is completed, execution returns to the intermediate code control unit 6.

In the VTR time-lapse section 9, the graphic display 1
The RGB signal output as 0 is converted to an NTSC signal, and a predetermined number of frames are recorded on a VTR (video recorder). When this process is completed, execution returns to the intermediate code control unit 6.

Through the above operations, frame images are sequentially generated and a moving image is created.

〔Example〕

Hereinafter, embodiments of the moving image creation method of the present invention will be described in detail.

FIG. 2 is a block diagram of an embodiment of the present invention, and FIG. 3 is a flowchart showing the processing procedure in this embodiment.

In this example, the source program ADL (^
ctton Definition Language
) ADL processor 12 for compilation of 11
The source program 11 is compiled into intermediate code and outputted to the intermediate code data file 13. Further, the ADL processor 12 generates matrix data and shape data of the object at a certain point in time necessary for creating the motion of the object, and performs zero or more processing to output them to the matrix data file 14 and the shape data file 15, respectively.
This will be explained based on the flowchart shown in the figure. One line of the source program is read (step S1), token analysis is performed (step S2), tokens are created, and incorrectly spelled words are discovered. When the token analysis is completed, the predetermined parameter arrangement for the keyword is checked (step S3), and it is determined whether the current keyword can be used. If there is no error, the values obtained from the values given as parameters are recorded in the intermediate code data file 13, matrix data file 14, and shape data file 15 in the keyword processing (step 34). The above operations from step 81 to step S4 are repeated until the source program ends (step S5
).

4 and 5 show record formats of intermediate code and matrix data, respectively.

The intermediate code consists of a record address part, an opcode part, and an operand part, and the matrix node data is
It is composed of a record address section and matrix elements of, for example, 4 rows and 4 columns. The following table shows examples of opcodes (instruction codes) and their meanings.

In FIG. 2, the intermediate code data file 13 includes:
There is a part that maintains an address relationship with the shape data. On the other hand, matrix data for creating motion is held in the matrix data file 14. The intermediate code control processor 16 sequentially reads intermediate codes from the intermediate code data file 13, and depending on the contents, activates the matrix calculation device 17 to perform matrix calculations, or activates the display device 1 to display the graphic display 19. It displays a video, or activates the time-lapse device 20 to take time-by-frame pictures of the screen.

This process is explained in detail in the flowchart of FIG. Step S5)
, when the intermediate code control brosé nosa 16 starts up (step S6), it accesses the intermediate code data file 13 and reads the intermediate code (step S6).
7). Next, the content of the instruction code is determined in step S8.
), perform the following operations depending on the instruction code.

If the instruction code is a matrix operation, the matrix operation device 17 is activated (step S9). The matrix calculation device 17 accesses the shape data file 15 and the matrix data file 14 based on the address of the shape data and the address of the matrix data. In steps SlO and 11), a vector x matrix operation is performed between the shape data and the matrix data. Action (Step 51
2) Record the calculation results in the shape data file 15 again (step 513).

If the instruction code is for display, the display device 18 is activated (step 514), the display device 18 accesses the shape data file 15 based on the shape data address passed from the intermediate code control processor 16, and displays the shape on the display 19. Display. After displaying, the execution of the intermediate code is temporarily stopped (step 515), and this state is maintained until a time-lapse completion signal is received.

If the command code is for frame-by-frame operation, the time-lapse device 20 is activated (step 516), and the image on the display 19 is recorded on the video recorder (step 517). after that,
The intermediate code control processor 16 determines whether or not the frame-by-frame shooting has been completed (step 318), and if the frame-by-frame operation has been completed, sends a time-lapse completion signal to the display device 18.

When the matrix calculation storage 171 display device 18 and the time-lapse device 20 each complete the above processing, they send a completion signal to the intermediate code control processor 16. The intermediate code control processor 16 checks whether all the data in the intermediate code data file 13 has been completed in step 51.
9) If the process has not finished, return to reading the intermediate code, and if it has finished, stop execution. In this way, a moving image can be created by sequentially generating frame images.

As is clear from the above examples, what corresponds to the video image is only the shape data at a certain point in time, and does not have images at all points in time, and the information for creating all the images is intermediate. Code data file 13. It is stored in the matrix data file 14 and shape data file 15.

〔Effect of the invention〕

As explained in detail above, according to the present invention, there is no need to previously store images (frames) that have been moved little by little in order to create a video, but instead it is possible to manipulate the shape data of objects that appear in a certain scene. A predetermined video can be created by simply holding the instruction information for the video. By using such a method, the data area for creating a moving image can be reduced, and the data can be easily saved and ported to other machines.
